title: [Influence of visual telencephalon (wulst) on directional selective neurons of pigeon's optic tectum (author's transl)].
abstract: The influence of the visual telencephalic projection area (Wulst) upon directional selective cells in the Pigeon's optic tectum was studied through reversible cold block of this telencephalic region. About half of the cells studied were affected during Wulst cooling. The effect was either a total loss or a marked reduction of the cell directional selectivity. These results indicate that the Wulst plays an important role in controlling the directional selectivity in the Pigeon's optic tectum.
